A chemical solution deposition process for preparation of highly (100)-oriented Ba(Zr0.05Ti0.95)O3 films was developed. The orientation degree of Ba(Zr0.05Ti0.95)O3 thin films prepared by this process can reach up to 99.1%. The electrical properties of the (100)-oriented films prepared by this process have been studied. The Ba(Zr0.05Ti0.95)O3 films with a thickness of about 270 nm show a dielectric constant of ∼740 and a loss tangent of ∼3%. The remanent polarization (2Pr) and coercive field (2Ec) are 3.2 μC/cm2 and 34 kV/cm, respectively.

Lithium and titanium co-doped NiO ceramics have been found to exhibit a giant low-frequency dielectric constant (ε~105), however, the same system thin films is not yet study. In the present study, Lithium and titanium co-doped NiO thin films were prepared by a chemical solution deposition method using 2-methoxyethanol as a solvent, nickel actate tetrahydrate, lithium acetate dihydrate and titanium isopropoxide as starting materials. The complex oxides such as NiO, Ni0.2O0.8 and NiTiO3 were formed for the Ni0.98Ti0.02O and Ni0.686Li0.294Ti0.02O thin films, and the addition of the lithium lead to the formation of Li2NiO2.888. The dielectric constant of Lithium and titanium co-doped Ni0.686Li0.294Ti0.02O thin films is about 426 at 100 Hz and much higher than that of the titanium-doped Ni0.98Ti0.02O.

In the present work, polycrystalline Bi0.67La0.33Fe0.5Sc0.5O3 thin films were synthesized using a simple and cost-effective chemical solution deposition process employing the spin coating technique. In order to check the feasibility of the fabrication of thin films on various types of substrates, the films were deposited on Pt-coated silicon, silicon, sapphire, corundum, fused silica and glass. Based on the results of thermogravimetric analysis of precursor and thermal stability study, it was determined that the optimal annealing temperature for the formation of perovskite structure is 600 °C. It was observed that the relative intensity of the pseudocubic peaks (001)p and (011)p in the XRD patterns is influenced by the nature of substrates, suggesting that the formed crystallites have some preferred orientation. Roughness of the films was determined to be dependent on the nature of the substrate.
